NPE when updating an existing RuleBase with new rules
-----------------------------------------------------

                 Key: JBRULES-1653
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1653
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 5.0.0-M1
            Reporter: Roel Adriaensens
         Assigned To: Mark Proctor


Steps to reproduce:

- create RuleBase, create Reader for .drl file, create Package with PackageBuilder and add it to the ruleBase
- now get the Package from the RuleBase, create a PackageBuilder with it, add extra rules to it from another .drl file (rules that didn't exist before), create the package and add it again to the RuleBase.

This results in a NPE being thrown:
java.lang.NullPointerException

Reason is that it tries to remove a rule from the RuleBase that does not exist in it.
